VALVE-REMOVING 'rooL.

To all whom it may concern:

Be it known that I, WILLIAM IV. PRICE, a citizen of the United States,residing at Elm Grove, in the county of Ohio and State of Vest Virginia,have invented new and useful. Improvements in Valve-Removing Tools, ofwhich the following is 'a specification.

This invention relates to valve removing tools or more particularlytothe class of tools used for compressing the springswhich hold puppetvalves upon their seats, in order that the spring retaining pin may bereadily removed from the stem of the valve and as readily replacedtherein, this being necessary in order to remove the valve from anengine which is ordinarily done for the pur pose of regrinding the facesof the valve and valve seat.

With the above and other objects in view, the invention consists in thenovel construction, combination and arrangement of parts, as hereindescribed, illustrated and claimed.

In the accompanying drawings Figure 1 is a perspective view of thecomplete tool.

Fig. 2 is a cross section through the same 7 taken adjacent to the yokering.

Fig. 3 is a fragmentary section through an internal combustion engine,showing one of the engine valves and the valve seating spring andillustrating the initial position of the valve removing tool of thisinvention.

Fig. 4 is a 'view similar to Fig. 3 the final position of the tool.

The tool contemplated in this invention comprises only three parts, 1designating the base of the tool, 2 the lever and 3 a yoke ring by meansof which the members 1 and 2 are adapted to be properly positioned inrelation to each other and the lever operated for compressing the valveseating spring.

4 designates a fragment of an engine, 5 one of the valves thereof,6 thevalve seat, 7 the valve spring, 8 the valve stem, and 9 the springretaining pin which is as usual inserted through a hole in said stem,all of said parts relating to the engine being of the usual constructionand arrangement.

showing The tool member 1 is practically straight Specification ofLetters Patent.

Patented-Mari 6', 1917;

throughout but the inner end thereof is flat- .tened and expanded inwidth to form a com paratively thin head 12 which is provided with anopen ended slot 13 adapted to embrace the push rod or push rod bushingabove referred to in the manner indicated in Figs. 3 and 4. The levermember 2 has its corresponding end made of less thickness and islaterally expanded to provide a relatively wide head 14 which like themember 1 is formed with an open ended slot 15 so that it may straddlethe valve stem 8 and engage the lower end of the valve spring 7 in themanner illustrated in Fig. 4. The inner end portion of the lever 2 isarched, deflected or curved as shown at 16 so that the head 14 thereofwill be practically horizontal when the parts of the tool are in theirfinal position as indicated in Fig. 4, thereby holding the spring. 7compressed in its relation to the valve stem 8.

In operation, the lever 2 and the ring 3 are slid backwardly a suitabledistance on the base member 1 as illustrated in Fig. 3. The head 12 isthen thrust under the pin 9 and around the push rod 10 or the bushing11. Then the pointed extremity of the head 14 is thrust under the lowerend of the spring 7. With the yoke ring 3 in the re lation to the lever2 as shown in Fig. 3, the outer end portion or handle of the lever isthen rocked toward the handle end of the base member 1 and as the lever2 fulcrums on the upper surface of the member 1, the spring 7 iscompressed until it assumes the position illustrated in Fig. 4. The yoke3 is then slid outwardly toward the handle portions of the members 1 and2 and serves to lock the handle portions of the two members togetherthereby maintaining the members 1 and 2 in the relation shown in Fig. 4.This enables the operator to use both hands in removing the pin 9. Afterthis is done, the ring 3 is again moved'into the relation to the member2 -shown in Fig.3. The member 2 together with the ring 3. are then slidoutwardly toward the handle end of the member 1 and the tool as a wholewith drawn from its useful position. This releases the spring 7 andenables the valve and also provided With a slot in the end thereof, anda yoke ring slidable length- Wise of the base and lever members andadapted to hold the lever member in rocking relation to the base memberin one position, and to prevent rocking movement of the lever memberWhen in another position.

In testimony whereof I affix my signature.

WILLIAM WEBSTER PRICE.
